Whenever a dev node that is not in use is opened with open(O_RDWR) udev triggers a flush in devtmpfs that briefly remove & recreate all the nodes for partitions on that device. This leads to commands accessing dev nodes during the flush to fail. In our case blkid and lsblk failed. These failures are hard to reproduce, have devastating effect on the partitioning operations and are not solved by using 'udevadm settle' as some of the kernel events are asynchronous. So, mainly, this commit stops udev from messing up with /dev nodes by initializing file descriptors for all storage devices then opening locks on them with flock. Setting locks stops udev triggering kernel partition rescan. Locks are set at the start of the partitioning operation and released at the end. For more details and similar cases see: o https://github.com/systemd/systemd/commit/02ba8fb3357daf57f6120ac512fb464a4c623419 o http://tracker.ceph.com/issues/14080 o http://tracker.ceph.com/issues/15176 This commit: o stops udev messing up with /dev nodes; o aborts install on critical failures; o adds retry for critical operations such as LVM cleanup or partition removal and creation.
